A distinctive feature of contemporary globalization in business regulation has been the emergence, across the diverse fields of economic and business law, of regulatory “networks” involving routinized transnational cooperation—both formal and informal—between institutional actors. The resulting global web of regulatory networks has transformed the legal environment in which business enterprises now operate. The classic liberal system of nation states coordinating activities at the government level has been displaced by a more fragmented system of multilevel networked governance in which new institutional and normative forms have proliferated, and which state sovereignty is increasingly disaggregated. As a consequence of the emergence of regulatory networks, the contemporary global legal order is more uncertain, de-centred and interconnected as the multiplicity of regulatory networks creates unprecedented coordination problems and increasingly complex interactions between legal orders. The intention of this book is to bring together scholars from different fields of economic and business law in order to map this emerging order of transnational regulatory networks. The book seeks to identify the main actors within a range of different networks and to identify and evaluate the diverse functions performed by such networks. Moreover, since networks raise a number of normative concerns (e.g. domination by experts, lack of transparency and circumvention of traditional democratic procedures/sources of legitimacy), networked governance requires a new normative foundation. Finally, the book will examine the meaning, value and limits of the “network concept” as an analytical tool for understanding and critically evaluating the emergent transnational regulatory order. This book has its origins in a conference organized on this issue by the Faculty of Law, Kyushu University in Fukuoka, Japan in February 2013. We are particularly grateful to Professor Toshiyuki Kono and the Faculty of Law for providing the financial support to have made this event possible, and to the students of the LL.M. and LL.D. programs in International Economic and Business Law, Kyushu University for their logistical help and participation.
